Installing the Expansion Hub
The Expansion Hub (1U high) can mount in a standard 19 in. (48.3 cm) equipment
rack or attach to a wall.
The Expansion Hub is shipped with #10-32 mounting screws. Another common rack
thread is #12-24. Confirm that the mounting screws match the rack’s threads.
Installing the Expansion Hub in a rack:
1. Insert spring nuts into the rack where needed or use existing threaded holes.
2. Place the Expansion Hub into the rack from the front.
3. Align the flange holes with the spring nuts installed in Step 1.
4. Insert the mounting screws in the appropriate positions in the rack.
5. Tighten the mounting screws.
Mounting the Expansion Hub to a wall:
1. Attach the L brackets to the Expansion Hub.
Using the screws that came with the Expansion Hub, attach the L brackets to the
Expansion Hub’s rack-mounting holes.
2. Hold the Expansion Hub to the wall in the position where it will be mounted and
mark the pre-punched L bracket holes onto the wall for drilling.
